The repair works on the 160m have been completed, and the cause of the problems is also known. For almost 30 years, I have been using plastic cable ties without any issues. To secure the 160m pulley at the top of the mast, I opted for the heavier version in black plastic. These cable ties seemed very strong, and tightening required the use of pliers. However, they still came loose, causing the pulley to fall down. There was also visible movement on the 80m vertical. In my opinion, the reason is that these cable ties are not resistant to temperature fluctuations and come loose during cold, windy nights.
